Need help simple calculation

Will drive for three days. Evey day he drives twice as many miles as the day before. After three days he has driven a total of 630 miles. How many miles did he drive on the first day?
A. 30 mi
B. 90 mi
C. 158 mi
D. 315 mi

Please tell me what could be the right answer.
I chose C. but it was wrong.

In addition to Jhevon's answer:

C: 158 mi on the first day - can't be the answer! Because of"Evey day he drives twice as many miles as the day before. So on the second day he drove 158*2 = 316
So after two days he drove 316+158 miles
On the third day he drove 316*2 = 632 miles

158+316+632 = 1106 miles
So D isn't correct either, because on the first day he drove more than 158 miles (and more than 630 miles in total)

x is the number of miles on the first day ....
soon the third day it's going to be 4x=630... to solve x= 630/4 = 157.5 (158)
why need to plus all?

Because you travelled 630 miles over a three day period. You need to take into consideration the number of miles travelled each day (because each day depends on the number of miles travelled the first day) when trying to answer the question.

The problem did NOT say that the distance driven on the third day was 630. It said "After three days he has driven a total of 630 miles." 630 was the total driven in all three days and "total" means "add".
